guy i work with was a flagship technician for saturn when they came to our town just conferred with him and the outlook is bleak as best i can say theres an issue with the unit containing the input and output shafts and the belt drive that is just notorious among those cars or rather that transmission it supposedly the same rating as the tranny found in an ion now placed into an suv platform so its overstressed the drives wear out sheer off and you lose any power transfer id have that thing looked at professionally i also wouldnt hold much hope for it being a cheap and easy repair coworker said he did more of those jobs on that car than just about anything else very consistent failure
